Description

When trying to inject parametrized bean to concrete required type (like the one below), StackOverflowError occures in GenericsUtil.satisfiesDependency

interface GenericFoo<T extends Comparable<T>> {
    T someMethod();
}
class FooImpl<T extends Comparable<T>> implements GenericFoo<T> {

    @Override
    public T someMethod() {
        return null;
    }
}

class Bar {
  GenericFoo<Long> foo;
}

Code to reproduce:

  //creating injection point of GenericFoo<Long>
  ParameterizedType injectionPointType = new OwbParametrizedTypeImpl(null, GenericFoo.class, Long.class);
  CoreReflectionFactory factory = CoreReflectionFactory.make(GenericFoo.class, ClassScope.make(GenericFoo.class));

  //constructing parametrized type manually
  TypeVariable<?> t = factory.makeTypeVariable("T", new FieldTypeSignature[]{
          ClassTypeSignature.make(Collections.singletonList(
                  SimpleClassTypeSignature.make(Comparable.class.getName(), false,
                          new TypeArgument[]{TypeVariableSignature.make("T")})))
  });

  ParameterizedType beanType = new OwbParametrizedTypeImpl(null, GenericFoo.class, t);
  GenericsUtil.satisfiesDependency(false, false, injectionPointType, beanType);
